Size effect of properties in hybrid of gold nanoparticles and calamitic mesogen

In this contribution we describe the synthesis and investigation of Au NPs functionalized with organic mesogenic groups which self-assemble into liquid crystalline phases. A nematic mesogenic liquid crystalline laterally reacts with functionalized gold via a siloxane group using Karstedt’s catalyst. Compared to earlier work where NPs were in the size of 1.5- 2.5 nm, we report here on larger than 5 nm sized particles.
